ABSTRAK
Latar Belakang: Sindrom Down adalah kelainan kromosom genetik yang disebut
trisomi. Pasien sindrom Down memiliki ekstra kromosom 21. Hal ini dikarenakan
adanya gagguan pembelahan kromosom yang disebut non-disjungsi atau
aneuploidi. Bertambahnya kromosom berdampak pada ketidak seimbangan
genetik, retardasi mental dan terganggunya fungsi fisik, intelektual bahkan
fisiologi tubuh. Beberapa gangguan atau masalah kesehatan terbesar yang dialami
oleh anak-anak dengan sindrom Down adalah gangguan pendengaran dan
perkembangan bahasa gangguan.
Tujuan: Penelitian ini bertujuan untuk menganalisis hubungan antara gangguan
pendengaran dengan perkembangan bahasa pada anak sindrom Down.
Metode: Penelitian ini menggunakan metode analytic observasional
retrospektive. Data diambil dari catatan medis pasien sindrom Down di RSUP dr.
Kariadi pada tahun 2008-2015. Sampel adalah anak sindrom Down yang
melakukan kontrol di RSUP dr. Kariadi Semarang. Pengambilan data berupa data
karakteristik, data fungsi pendengaran kedua telinga yang dilakukan pemeriksaan
BERA , dan data perkembangan bahasa yang diperiksa dengan DDST. Uji
statistik dilakukan dengan uji Chi-square dan uji Fisher .
Hasil: Penelitian ini menggunakan 32 sampel anak sindrom Down. Sebanyak 8
(25%) subjek dengan pendengaran normal dan 24 (75%) adalah subjek dengan
gangguan pendengaran. Analisis hubungan gangguan pendengaran ringan dengan
perkembangan bahasa (DDST) mempunyai nilai p = 1,00. Hubungan gangguan
pendengaran sedang dengan perkembangan bahasa (DDST) mempunyai nilai p =
0,538. Dan hubungan gangguan pendengaran berat – sangat berat dengan
perkembangan bahasa (DDST) mempunyai nilai p = 0,569.
Kesimpulan: Tidak ada hubungan gangguan pendengaran pada perkembangan
bahasa pada anak sindrom Down.
Kata kunci: Down syndrome, gangguan pendengaran, perkembangan bahasa
(DDST).

ABSTRACT
Background: Down syndrome is a genetic chromosomal disorder called trisomy.
Patients with Down syndrome have an extra chromosome 21. This is because of
non-disjunction or aneuploidy of the chromosomes. Increased chromosomal
imbalance impact on genetic, mental retardation and disruption of physical
functions, intellectual and even physiology. Some of the largest health problems
experienced by children with Down syndrome are hearing impairment and
impaired language development.
Aim: To analyze the correlation between hearing impairment and language
development in Down Syndrome children.
Methods: This study uses an observational analytic retrospective. Data taken
from the medical records of Down Syndrome patients in the dr Kariadi Hospital
Semarang in 2008-2015. The data include characteristic of the subject, hearing
function on both ears with BERA examination, and examined language
development with DDST. Statistical tests performed by Chi-Square test and
Fisher's exact test.
Results: This study used 32 samples of children with Down syndrome. A total of 8
(25%) us subjects with normal hearing and 24 (75%) is subjects with hearing
impairment. Analysis of the relationship beetwen mild hearing impairment and
the development of language (DDST) has a value of p = 1.00. Analysis of the
relationship beetwen moderate hearing impairment and the development of
language (DDST) has a value of p = 0.538. And the analysis of the relationship
beetwen severe – profound hearing impairment and the development of language
(DDST) has a value of p = 0.569.
Conclusion: There is no correlation between hearing impairment and language
development in children with Down syndrome.
Keywords: Down syndrome, hearing impairment, language development (DDST).
